Does the priest recite the blessing, since the benefit redounds to him; or does the child's fath recite it, since it is he who carries out a religious duty?<span class="x" onmousemove="('comment',' The religious duty is primarily his, since any priest could receive the redemption money.');"><sup>3</sup></span> He could not answer it, so he went and asked it at the schoolhouse, and he was told: The child's father recites both blessings. And the law is that the child's father recites both blessings.<span class="x" onmousemove="('comment',' Rashbam: this story is quoted here because the Mishnah too treats of two blessings.
